The present invention relates to methods and systems (100) for densifying liquids, specifically the densification of cryogenic propellants. A preferre d system of the present invention subcools and densifies liquid propellants by utilizing a countercurrent gas or liquid flow. The countercurrent flow preferably utilizes a gas having a lower boiling point than the propellants. A packed tower may then be used, at or above atmospheric pressure, to introduc e the countercurrent flow to the propellant. This methodology avoids the costs and problems associated with subatmospheric operation. A preferred embodimen t is directed toward the densification of liquid oxygen and liquid hydrogen. Systems and methods of the present invention may also be used to densify oth er liquids in similar fashion. |
